Verified step by step guidance1
Identify the process described: water boiling and turning into steam is a phase change from liquid to gas.
Recall that a physical change involves a change in the state or appearance of a substance without altering its chemical composition.
Understand that during boiling, water molecules remain H\_2O; they do not break down into atoms or form new substances.
Recognize that a chemical change involves the formation of new substances with different chemical properties, which does not happen here.
Conclude that boiling water is a physical change because it changes state but the chemical identity of water remains the same.
